Engine Cooling problem
2001 Hyundai Sonata 6 cyl Wheel Drive Type unknown Automatic 75,000 miles
----------------------------------------------------------------
I am not a mechanic but have had extensive history with this one problem so here is what I've got. My in-dash temp gauge reads hot when I get about 40mph and above. No noticed performance loss, just the in-dash temp guage says it's overheating Just bought the car, the coolant looked like mud, very dirty. I replaced the thermostat, had the system flushed, replaced the radiator, replaced the temp-sensing unit.
Have had my share of mechanics and all of their work and/or suggestions have failed. The car runs pretty well. Shot the engine block with an IR gun and it doesn't seem like it really IS getting hot, temp reads around 200*F on the outside of the block.
Doesn't seem like the cooling system is working how it is supposed to. Thermostat still doesnt seem to work properly. Doesn't "Drink" when I think it should, etc. The heat doesn't get hot and the AC doesn't seem to get cold either, which I'd imagine is related. One mech. told me it was a head gasket leak but all other say no way. No performance issues, oil and coolant don't seem to be mixing, plus I had some test done where the put a gas in the system or something and that checked out ok for the head gasket.
Help, I can probably offer more insight, this has been a long time deal and I have tried everything I can think of all all that has been suggested thus far.
